A gas fireplace built for St. Johns County living.

Most propane gas fireplace and insert installations in the Fruit Cove area run $4,000 to $9,500, depending on the unit, whether you're converting an existing wood-burning fireplace, and whether a new propane tank needs to be set. Homes that already have a propane tank for a range or water heater are typically on the lower end, since the installer just needs to run a new line. Homes starting from scratch—including tank purchase or lease, line run, and a direct-vent fireplace or insert—land toward the higher end. A local dealer will give you a firm number after seeing the space.

Most of Fruit Cove and the surrounding St. Johns County communities run on propane rather than municipal natural gas—natural gas mains haven't been extended through many of the newer subdivisions off SR-13 and Racetrack Road. That's not a downside for a fireplace: modern direct-vent units run equally well on propane, and your installer will set the correct orifice and regulator for the fuel you have. If you're building new or doing a larger renovation, some homeowners opt for a buried propane tank to keep the yard looking clean—worth asking your dealer about if aesthetics matter to you.

This is one of the best reasons to choose gas in this part of Florida. Both Florida Power & Light and JEA see extended multi-day outages during hurricane season, and a propane fireplace with intermittent pilot ignition (IPI) keeps running on battery backup when the grid drops. Valor units take it a step further—their pilot generates its own electricity through the thermocouple, so there are no batteries to remember at all. For a Fruit Cove household riding out a storm, that's the difference between a dark, silent house and a warm, lit room with a working heat source. Ask your local dealer about ignition type specifically if outage performance matters to you.

Vented, direct-vent units are the better call here. Vent-free fireplaces release combustion byproducts—including water vapor—directly into the room, and Fruit Cove already sits in one of the more humid corners of the country for much of the year. Adding more moisture indoors is the last thing a Florida home needs; it can aggravate condensation and mold issues that are already a concern in this climate. Direct-vent units draw combustion air from outside and exhaust it back outside through a sealed pipe, so indoor humidity and air quality aren't affected. Vent-free units are technically legal in Florida with room-sizing restrictions, but most local dealers steer Fruit Cove customers toward direct-vent for this reason.

A gas fireplace is a fully built-in, framed unit—the right call for new construction or a remodel without an existing firebox. A gas insert drops into an existing masonry or wood-burning firebox and uses the existing chimney as its venting path, which is common in older Fruit Cove homes built with a traditional wood fireplace that rarely if ever got used. A gas log set is the simplest option—decorative logs placed inside an existing open fireplace—but it's the least efficient and, in a vented configuration, sends most of the heat straight up the chimney. For most homeowners here converting an unused wood firebox, an insert delivers the best mix of heat output and efficiency.

Yes. St. Johns County requires a building permit for gas fireplace installations, and any new propane line work must be done by a licensed gas contractor as part of that permit. Most hearth dealers in the area handle the permitting through the St. Johns County Building Services Division as part of the installation, so you're not coordinating separate trades or paperwork yourself. If you're setting a new propane tank, your propane supplier will typically handle the tank placement and inspection requirements separately.

Plan on an annual inspection, ideally before hurricane season ramps up in early summer so you know the unit will work if you lose power later. Florida's humidity and insect activity are harder on gas fireplace components than a drier climate would be—wasps and other insects are known to nest in vent terminations if a unit sits unused over a mild winter, which can block proper venting. A certified technician will check the burner, pilot, gas connections, and venting, and clear out anything that's taken up residence since last season.

With winter lows averaging 47°F and only a short, mild heating season each year, there's simply no real heating load for wood to solve here—Fruit Cove's climate is nothing like the cordwood-heavy winters of a place like Bozeman, MT. Wood and pellet stoves are essentially not stocked by hearth dealers in this market. That said, some older homes in the area were built with a traditional wood-burning fireplace that now sits unused most of the year. If that's your situation, converting it to a gas insert is usually the more practical path—you get real heat output for the rare cold night and none of the upkeep of firewood in a climate that doesn't call for it.

Electric fireplaces are the lower-cost entry point—typically $400 to $1,200 installed—and they run on either Florida Power & Light or JEA service (residential rates run roughly $0.124 to $0.137 per kWh locally), so there's no propane tank or gas line to deal with. The tradeoff is that electric units are useless during a power outage, which matters in a hurricane-prone area. Gas costs more upfront but keeps working when the grid doesn't, and it produces real, radiant heat rather than a fan-driven approximation. For a primary living space where you want backup capability, gas is usually the better fit; for a bedroom or secondary room where ambiance is the main goal, electric can make sense.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.
